When your dog is panting heavily and has a swollen belly, it’s a combination of symptoms that can point to serious and potentially life-threatening conditions. This situation often requires urgent veterinary assessment.
We outline the common reasons why a dog panting with a swollen belly occurs, what you can do at home, and when to seek veterinary help.
Dog Panting and Swollen Belly — Why It Happens
Dog panting with a swollen abdomen is often a sign of distress, pain, or a dangerous internal condition. It may be caused by gastric dilatation-volvulus (bloat), internal bleeding, heart disease, fluid buildup from organ problems, severe infections, or late-stage pregnancy complications.
Because many of these conditions progress quickly, recognizing the symptoms and acting promptly is critical.
Dog Panting and Swollen Belly: Common Causes
Gastric Dilatation-Volvulus (Bloat)
Bloat is one of the most urgent causes of a swollen belly with panting.
It occurs when the stomach fills with gas and twists on itself, cutting off blood supply.
Dogs show signs such as restlessness, unsuccessful attempts to vomit, drooling, and rapid breathing.
Without emergency surgery, GDV can be fatal within hours.

Ascites (Fluid Buildup)
Ascites is the accumulation of fluid in the abdomen, often linked to heart failure, liver disease, or certain cancers.
This fluid causes the belly to swell, making breathing more difficult and triggering panting.
Dogs may also appear lethargic, have reduced appetite, and show signs of weakness.
Treatment focuses on the underlying cause and relieving fluid pressure.
Heart Disease
Heart conditions, especially congestive heart failure, can cause fluid to build up in the abdomen.
The heart struggles to pump blood effectively, leading to back pressure in the veins and fluid leakage into the belly.
Panting occurs as the body tries to compensate for reduced oxygen delivery.
Coughing, fatigue, and exercise intolerance are often seen alongside these symptoms.
Internal Bleeding
Trauma, ruptured tumors, or certain clotting disorders can cause bleeding into the abdominal cavity.
The belly swells as blood accumulates, and panting results from pain, blood loss, and shock.
Other signs include pale gums, weakness, and collapse.
Immediate veterinary intervention is essential to locate and stop the bleeding.
Severe Infections (Peritonitis)
Infections inside the abdominal cavity can cause inflammation and swelling.
Panting occurs due to pain, fever, and the body’s stress response.
The abdomen may feel hard or extremely tender to the touch.
These infections require hospitalization, antibiotics, and sometimes surgery.
Pregnancy Complications
In late pregnancy, a swollen belly is normal, but panting can indicate labor is starting or that complications such as dystocia (difficult birth) are present.
Prolonged panting without delivery, signs of distress, or foul-smelling discharge require urgent veterinary care.
Quick intervention can save both the mother and puppies.
What to Do If Your Dog Is Panting and Has A Swollen Belly
If your dog has these symptoms, keep them calm and limit movement to prevent worsening their condition.
Do not attempt to press on or manipulate the belly, as this can cause further injury.
Ensure they have access to fresh water, but do not force drinking.
Move them gently to a cool, quiet place while arranging immediate veterinary attention.
Because many causes are emergencies, prompt transport to a vet is the safest course of action.
When to Call or Visit Your Vet
Seek veterinary help immediately if your dog’s swollen belly appears suddenly, is accompanied by panting, or is causing obvious discomfort.
Other urgent signs include collapse, pale gums, difficulty breathing, vomiting, or signs of shock.
Even if the swelling seems mild, underlying causes like heart disease or fluid buildup can be serious.
Early diagnosis improves the chances of a successful outcome.
